Answer:

x=-3/19

y=39/19

Step-by-step explanation:

the equations can be written as the following system

[tex]x+3y=6\\-12x+2y=6[/tex]

If the second equation is multiplied by 3/2 it will become -18x+3y=9

If that equation is then subtracted with the first you will obtain the following

-19x=3, it means x=-3/19

The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19
